The average slope of a parcel is calculated using the following formula: S = 100(I)(L)/A, where:
S = Average slope (in percent)
I = Contour interval (in feet)
L = Total length of all contour lines on the parcel measured from where the contour lines intersect with the property lines of the parcel (in feet)
A = Area of subject parcel (in square feet)
